Section 3: Consideration of high-efficiency alternative systems

3.1 Before building work starts on a new non-domestic building, the person undertaking the building work must analyse the technical, environmental and economic feasibility of using high-efficiency alternative systems in the building design. This analysis should be considered when designing the building.

3.2 The building control body should be notified that the analysis of high-efficiency alternative systems has been undertaken, that it is documented and is available to be verified. The document should state whether high-efficiency alternative systems have been included in the building design.

The documented results of the analysis should be retained for the building control body to inspect upon request.

3.3 The analysis may be carried out for individual buildings, groups of similar buildings, or for common types of buildings in th
